Forecasters' discussion

From the National Weather Service office in LOT, issued 4 hrs ago

Key Messages

- Some ground fog may develop within 10-15 miles of Lake Michigan during early morning hours the next few days. Any fog would then quickly dissipate after sunrise.

- An extended period of dry and above to much above average temperatures is expected through the upcoming weekend.

Discussion

Issued at 154 AM CDT Tue Oct 20 2026

No significant weather is expected through the upcoming weekend with above to much above average temperatures each day. Generally light winds should allow weak lake breezes to form each of the next several afternoons, but only result in slightly cooler conditions right near the lake. A modest increase in moisture in the wake of the afternoon lake breezes could allow for some ground fog to form during the early morning hours the next few days. Otherwise, look for mostly sunny conditions for the remainder of the work week.

Aviation

Issued at 1230 AM CDT Tue Oct 20 2026

Key Aviation Messages for the current TAF period:

- Patchy fog possible around sunrise.

Winds are expected to be light and variable, if not outright calm through the overnight. There is a chance for patchy fog toward daybreak for Chicago terminals, with better chances closer to the lake. There is still uncertainty with how low visibilities will go, but will be monitored through the night. But the expectation is that any fog that does form should dissipate after sunrise for a return to VFR.

Light winds will prevail through the day, mostly out of the east. There is another chance for patchy fog tomorrow morning. Given there is little change to the overall weather pattern tomorrow, would like to see how this morning plays out first before adding fog to the TAFs for Wednesday morning.
